Accuracy to 1 meter??

HI - Brand new here and trying to catch up on the technology....and a bit lost. I read accuracy of waypoints is slowly becoming cost effective for a handheld device and need to know if its here....and any recommendations.We have a specialized plant nursery with over 500 plants (waypoints?) that are planted in a 3' x 4' grid. Hardest part of this is keeping track of the names of the cultivars. Are there hand held devices out there that can give me 500 named waypoints and is accurate to about 3 ft? Thanks for the help

I doubt that the GLO is accurate enough for your application however. But the nice thing about bluetooth receivers is that they can work with hundreds of apps on iOS and Android phones and tablets. SXblue makes some very accurate bluetooth devices. But I think you're getting into thousands of dollars again..

Oh...you know so little about the nuts and bolts of managing 300 plus individual plants that are cut down to the ground every season, where stakes are heaved up and out during the winter, customers too lazy to bend over to read them and insist on pulling them out to read, where semi mechanized weeding machines have trouble avoiding, thus breaking the markers, much less fading writing markers that claim to be permanent and plants that refuse to stay in a perfect grid alignment over the years. More?

No...meant to put a smiley face on my issues...and to note how things are much more complicated for the professional then this non-professional (nurseryman) thinks. A teeny bit miffed however thinking that I never thought out or tried "tags and a paper grid to work this out.

You might want to look into the technologies used for indoor positioning systems. Of course, you are not inside a building, but these systems can provide high accuracy in a controlled environment. Not a subject that I know anything about myself though. :)

@dmq400 …Sorry, I didn't mean to offend. You are right, I know nothing about your business, so I should have just not posted rather than making a useless suggestion. I hope you can find something that works.

BTW, I should add that the OP's topic of "accuracy to 1 meter" doesn't really describe a device that would fit his needs. You would need sub-meter accuracy to positively identify objects in a 3'x4' grid.

"1 meter accuracy" is generally taken to mean +/- one meter. So, if you mark a waypoint and then return to it later, you would expect to be somewhere inside a one-meter radius (2-meter diameter) circle centered on the original point. Your plants are too close together to be uniquely identified at that resolution. And it's even worse that that, because "1 meter accuracy" doesn't really mean "1-meter accuracy"... there's some "fine print" associated with that specification along the lines of "1-meter accuracy 75% of the time". If that was the actual spec, then 25% of the time you could be sent someplace wildly wrong.
